The file gamedata\textures\ui\ui_icon_equipment.dds looks messed up. This is the file which displays icons for stuff you see in the game, weapons, armor everything. It looks like the person did not have enough inventory space for the extra weapons and added an extra bit of space beside the main inventory area. If you have gimp or photoshop with the dds plugin, open the file and you will see straightaway it looks completely messed up. Besides that, weapons.ltx has all the new weapons added except for the famas assault rifle. It has a mesh and it's included in the icon_equipment.dds file but it has no w_famas3.ltx file.

I didn't experienced any crashes when open inventory. My problem is game crash when I'm trying to equip M82 Sniper Rifle. I still hope You'll check it. BTW: If You are able to fix that... Could You upload somewhere fixed gamedata folder ? But please check it all if You can.

Off top: I just saw You have Medieval II, great title. If You have kingdoms expansion You can download Third Age mod from TW Center, apply patches 1.1 and 1.2 and try out my small work Link

off topic, I stopped playing med 2 when I realised the cavalry were totally useless in a charge. Maybe nothing but open any other weapon file in the configs\folder and one of the lines they all have is condition_queue_shot_dec=

The w_m82.ltx file and w.awm.ltx don't have this line in the files, under the line condition_shot_dec = 0.0002

Still crash when I'm trying to equip m82...Pistols are working fine. AWP and m82 crash game when trying to equip. Steyer Aug crash game when I'm trying to add it to inventory (by spawner).EDIT: Do You know how to edit armor bullet protection ? I can edit anything else except this...
